The 4M method is a simple problem-solving tool that allows us to brainstorm, identify, and group potential factors that cause problems. To be more effective during the implementation of 4M method (Ishikawa), we could use an additional Checklist. The 4M Checklist is an essential part of completing the perfect implementation of the 4M method. There is a standard set of questions that you should ask and review during the brainstorming phase. These questions have a goal to help you identify potential causes, but also to drive you systematically through the problem-solving process. Usage of the checklist is prevention to not forgetting some of the hidden or not-so-obvious causes.
